XR16M752/XR68M752  
HIGH PERFORMANCE DUART WITH 64-BYTE FIFO  
REV. 1.0.2  
MAY 2007  
FEATURES  
GENERAL DESCRIPTION  
1.62 to 3.6 Volt Operation  
1
The XR16M752/XR68M752 (M752) is a high  
performance dual universal asynchronous receiver  
and transmitter (UART) with 64 byte TX and RX  
FIFOs. The M752 operates from 1.62 to 3.63 volts. It  
is pin-to-pin and software compatible to the  
TL16C752B and SC16C752B, but with additional  
features such as a programmable fractional baud rate  
generator, automatic RS-485 half-duplex direction  
control, infrared mode and 8X and 4X sampling rate.  
The standard features include 16 selectable TX and  
RX FIFO trigger levels, automatic hardware (RTS/  
CTS) and software (Xon/Xoff) flow control, and a  
complete modem interface. Onboard registers  
provide the user with operational status and data  
error flags. An internal loopback capability allows  
system diagnostics. Each channel is independently  
programmable for data rates up to 16 Mbps at 3.3  
Volt with a 4X sampling rate. The XR68M752 has an  
additional 16/68# pin to select between the Intel and  
Motorola bus interface. The M752 is available in the  
48-pin TQFP and 32-pin QFN packages.  
Pin-to-pin and software compatible to TI’s  
TL16C752B and Philips’ SC16C752B in the 48-  
TQFP package  
Two independent UART channels  
Data rate of up to 16 Mbps at 3.3 V  
Data rate of up to 12.5 Mbps at 2.5 V  
Data rate of up to 8 Mbps at 1.8 V  
Fractional Baud Rate Generator  
Data sampling rates of 16X, 8X and 4X  
Transmit and Receive FIFOs of 64 bytes  
Programmable TX and RX FIFO Trigger Levels  
Automatic Hardware (RTS/CTS) Flow Control  
Automatic Software (Xon/Xoff) Flow Control  
Halt and Resume Transmission Control  
Automatic RS-485 Half-duplex Direction  
Control Output via RTS#  
Wireless Infrared (IrDA 1.0) Encoder/Decoder  
Automatic sleep mode  
NOTE: 1 Covered by U.S. Patent #5,649,122
